CARBURE'HNG APPARATUS.

Specification of Letters Patent.

Patented May 7, 1907.

. To all whom it may concern:

Be it known that LIROBERT G. SPEER, a citizen of the United States of America, and a'resident of the city of St. Louis and State of Missouri, have invented certain new and useful Improvements in Oarbureting Apparatus, of which the following is a specification.

This invention relates to an apparatus for carbureting air for lighting and heating purposes, and has for its object to provide a simple and durable structural arrangement and combination of parts whereby an efiective carbureting of the air is effected, and the flow of air through the apparatus rendered constant with a consequent avoidance of the fluctuations in the flame of the burners where the combustion of the carbureted air takes place, all as will hereinafter more fully appear. I

The accompanying drawing is a central vertical section of an apparatus embodying the presentinvention.

Referring to the drawings, 1 represents the carbureter of the present apparatus, consisting of a closed casing provided with an induction pipe 2 near its lower end, and a corresponding eduction pipe 3 at its upper end. 4 is a porous partition arranged near the rind-height of the carburetor casing, todi vide the same into a lower containing cham' her for the supply of gasolene, and into an,

upper containing chamber for the carbureted air.

5 is a distributing tank arranged centrally in the upper end of the carburetor casing and i provided with a contracted outlet orifice o at its lower end.

6 is a distributing trough arranged beneath the distributing tank and adapted to receive the limited outflow from the same, and in turn discharge the gasolene down upon the porous partition 4 in the bottom of said tank.

7 is a pipe connecting the lower end of the distributing tank 5, with the lower part of the carbureter casing containing the supply of gasolene. I

8 is a check valve arranged in the pipe 7 to prevent a back flow of the gasolene from the distributing tank 5, aforesaid.

9 is a simple acting pump, arranged and operated in the manner'hereinafter described, and connected by pipe 10 with the top of the distributing tank 5 the arrangement is such that with an active stroke of such pump the air will be exhausted from the upper end of the tank 5, and in consequence a fresh supply of gasolene will be drawn into said tank through the pipe 7 from the main supply in the lower end of the carbureter casing.

11 and 12 are a pair of stationary pump cylinders, in the form of open top vessels the walls of which are formed double to provide annular water containing chambers or seals 13 and 14 for the movable pistons of the pumps or compressors.

15 and 16 are a pair of inverted bell pis tons, having annular depending skirts which dip into the annular seals 13 and 14, as shown.

With the described arrangement of pump cylinders and pistons, the usual closed central air compression chambers 18 and 17 are provided, and the capacities of which are alter-- tical reciprocation of the pistons with rel'a- 'tion to the cylinders, to alternately draw in air from the outer atmosphere,and compress and forcesaid air to other portions of the ap paratus, as hereinafter more fully set. forth.

19 is a crown plate closing the to of the inner vertical wall of the pump cylin er 1 1 to form a chamber 20 underconstant and nor mal. atmospheric pressure, and which to this end is provided with an orifice 21 forming a constant communication with the outer air.

22 is a check valve controlling an inlet passage tl'irough said crown 19, and through which air is admitted to the compression chamber 17 of the pump.

23 is an outlet pipe communicating with I the compression chamber 17, and extending to the stora e and pressure regulating tank hereinafter described; such pipe is provided with a branch portion 24, which connects with the compression chamber 18 of the other pump to act as an inlet-outlet pipe to said chamber in the normal operation of the chamber.

25 is a supplementary inlet passage to the compression chamber 18, and 26 is a check valve controlling said passage, The said passage and valve are supplementary to inlet- 3 outlet branch pipe .24, and in some cases may requisite downward stress in attaining the desired compression of the air passing through the apparatus.

33 is a check valve at the eduction end of the pipe 23, before described, to prevent a reflux of the compressed air from the storage andi pressure regulating chamber 27; aforesai I 34 is a horizontal beam attached to the upper ends of the bell pistons 15 and 16 to form a common operating connection tor the two .12 5

pistons.

. 35 1s a flexible connection attached centrally to the beam 34:, and having in turn op-.

erative connection with a suitable automatic motor, so as to receive and impart simultain the operation. of the apparatus.

neous u ward movements to the pistons aforesai at proper intervals-of time required hich L,

automatically operating motors are quite common in the present type of apparatus and does not constitute any part of the present invention.

' 36 is a vertical guide rod fixedly seeuredto eeaese in a fixed tube 37 secured to a stationary part of the apparatus, and adapted to impose Vertical movement on the bell pistons of the pumps.

38 is a vertical rod extending from one end of the beam 34, and connected to the piston of the single acting pump 9, before described, and adapted to impart movement to said piston in unison with the bell pistons of the air pumps aforesaid. As so connected the pump 9 willhave a central arrangement in the compression chamber 18, as shown.

Having thus fully described my said invention, What I claim as new and desire to secure by Letters Patent, is

In a carbureting apparatus, the combina tion of a carb-ureter, a pair of tank and bell pumps, one of which is formed with an interior chamber open to atmospheric pressure,

vmeans for imparting simultaneous reciprocation to said pumps, a storage and pressure regulating tank arranged in said interior chamber, a simple acting pump arranged in the interior of the other tank and bell pump and adapted to circulate the fluid contents of the carbureter, and pipe connections between the tank and bell pumps and the storage tank and between the storage tank and the carl'iureter.
